Hi there.
You must have a drain some where.
Make sure the brake light are NOT staying on. if they are, it will drain the battery. this is due to faulty brake light switch.
I think the ESP light is related to the brake light switch.

I have a mercedes 2002 c240 and it wont start the fan comes on when i turn the switch. I thought it could be the engine control module or a fuse, not sure can you assist?


Hi Mate
Don't think to deep about the engine control module its highly unlikely, Check the battery connections are tight and confirm the battery voltage It would be best to connect a boost/jump battery
to confirm its not a simple low voltage battery, Dont rely on measuring the battery with a volt meter it could show 12v but under load will drop to below 9 and cause a non start

How can I test a Mercedes 2002 C240 Cooling fan on the bench?


Connect 2 wires to fan plug, w/ other end of wires touch to battery terminals (disconnect battery to make sure you don't accidentally touch the wires together while doing this, as you can damage the electrical system). When you touch to the batt. terminals, the fan should kick on. If it doesn't, the fan motor is shot, if it does turn on, it is a relay that is bad, not signaling the fan to turn on when it should (as engine temp goes up).
